The Mercedes G-Class SUV has a 5.5L, 382-horsepower V-8 engine with an EPA fuel economy of 12 MPG city and 15 highway. Adaptive Highbeam Assist uses a dedicated camera to scan the road ahead for the lights of other vehicles. Based on their calculated position, it varies the headlamps infinitely, not just to high or low beams, to maximize illumination without causing glare for other drivers.
